On March 28, the 220kv830MVA three-phase generator transformer developed by China XDC for Shandong Hongqiao New Material Co., Ltd. Zou Ping 1 Power 6×660MW unit was tested in one time, and the functional indexes were satisfied or better than the requirements of the national specifications and technical agreements.
The 660MW unit belongs to ultra supercritical unit, and its power and environmental protection function are superior to those of small capacity unit. With the world's increasing attention to pollution control and haze reduction, the market prospect of ultra-supercritical large capacity generator sets is very broad. Prior to this, the booster transformers for ultra-supercritical units developed by China XD are mainly concentrated in the 500kV and 750kV fields, and similar commodity sequences in the 220kV grade are still single. This commodity is the 220kV three-phase integrated generator transformer with the largest planning capacity of our country's west power at present. How to control the leakage of magnetic field in the body, the planning of large current lead wire construction, to ensure that the structure is compact and easy to transport is the key skill. Based on the current national standard specification and the existing planning and manufacturing skills of 220kV transformer, the skilled personnel of China West Electric Power Co., Ltd. (XDC) carried out skill innovation and scientific research to solve the problems such as large capacity, high impedance, large weight, large volume, severe loss request and difficult transportation of this transformer.
This 220KV 830MVA three-phase generator transformer research and development success, all improved our country western power huge capacity transformer planning and making key skills, constitute a completely independent intellectual property rights of skills, promote the promotion of commodity skills and upgrading, for the sustainable development of the company to provide a strong skill support.
